I try to Katalon integrate with Jenkins based on the CentOS 7 & there is the issue in that.The Exception mentioned in the below.

Test Cases/Common/tc\_Login FAILED because (of) java.awt.HeadlessException:

No X11 DISPLAY variable was set, but this program performed an operation which requires it.

Please help me to find a solution for that.

Have you tried running the command using headless mode?
